What is the least count of the vernier callipers ?
If main scale division = M and vernier scale division = V 9M = 10 V (10-1) M = 10V 10M - M = 10V 10 (M - V)= M, M,(M-V) = M/10 = least count.
What is the least count of commonly available vernier ?
Least count = M /n = 1mm/10 = 0.1 mm = 0.01cm
When the zero mark on the vernier scale lies towards the left side of the zero mark of the main scale, when the jaws are connect, then what will be the zero error ?
Here zero error is positive, so zero. correction is negative, as zero correction = - (zero error)
When the zero mark on the vernier scale lies towards the right side of the zero mark of the main scale, when the jaws are in contact, then what will be the zero error ?
Here zero error is negative, so zero correction is positive.
If observed reading is OR, corrected reading is CR, zero error in ZE and zero correction in ZC, then what will be the possibility ?
Corrected reading = Observed reading - zero error $ \Rightarrow CR = OR - ZE $ $ \Rightarrow CR = OR + ZC $ $ \Rightarrow ZC = CR - OR $
When the jaws of a standard vernier are together, the 6th vernier scale division coincides withthe 6th main scale division, then what in the zero error ?
vernier divisions are smaller then the main scale dividions (9M = 10V), the zero of the vernier must be on the right side of the zero of the main scale. Here zero error is positive.$ \Rightarrow Zero error = 6M -6V = 6(M_V ) = 6 (0.1 mm) = +0.6 mm $
When the jaws of a standard vernier are together, the 6th main scale division coincides with the 7th vernier scale division, then what is the zero error ?
Zero erroe = 6M -7V = (7M -&V) -M = 7 (0.1 mm ) - 1mm = -0.3 mm
In an anusualvernier, 9 vernier scale divisions coincide with 8 main scale division, then what is the least count of the vernier ?
8M = 9V \Rightarrow 9M - M = V 9(M-V) = M or (M -V ) = M/ 9 = 1 /9 mm
In an unsual vernier, 10 vernier scale divisions, coinside with 8 main scale divisions, thenwhat isthe least count of the vernier ?
$ 8M = 10V \Rightarrow 10M -2M = 10V , 10(M-V) = 2M (M -V ) = 2M /10 = 0.2 mm$
Physics is one of the basic disciplines in the category of.......... sciences.
Physics is categorized as a natural science because it involves the study of the natural world and the laws that govern it. Natural sciences include fields such as physics, chemistry, biology, and earth sciences.
